      The mean NVGT value decreases from 12 days to less than 1 day in eastern North America over – (the overall mean from all sites is in eastern US vs. by model prediction over eastern North America in , this discrepancy might be due to the lack of Canadian data in the year ).

Ozonesonde observations over North America by Wayne S. Hering Download PDF EPUB FB2

In this study ozonesonde profiles collected in June, July and August of, and from 18 sites across North America north of 40° N latitude are used to determine ozone Author: Omid Moeini, David W. Tarasick, C. Thomas McElroy, Jane Liu, Mohammed K.

Osman, Anne M. Thompson, Ma. The CMDL network of eight ozonesonde sites makes weekly ozone vertical profile observations from the surface to about 35 km using electrochemical concentration cell (ECC) ozonesondes.

Three of these sites, Boulder, Colorado, Hilo, Hawaii, and South Pole, Antarctica have records of at least 15 years in length covering a significant portion of. Tropospheric Ozone Over the North Pacific From Ozonesonde Observations S.

Oltmans', B. Johnson', J. Harris', A. Thompson', ozone over the North Pacific emerges. At all of the sites there is a pronounced spring in Asia and North America. Continental Asia and western coastal North America Cited by: Articles in periodicals and books: Abstract: This study evaluates simulated vertical ozone profiles produced in the framework of the third phase of the Air Quality Model Evaluation International Initiative (AQMEII3) against ozonesonde observations in North America for the year Cited by: 1.

Averaged values from daily ozonesonde profiles at five sites over the North Atlantic in Augustfound O 3 mixing ratios of 25 ppbv at the surface and ∼37 ppbv at 1 km [Oltmans et al., ].

[5] A number of tropospheric chemistry field missions (e.g., WATOX, NARE I and II, and ITCT) have been dedicated to understanding the chemical Cited by: The ECC ozonesonde has been reported to have a precision of 3–5% and an accuracy of approximately 5–10% at most altitudes below 28 km [27,30,31].

The ozonesonde observations in Pohang are conducted once a week, at approximately UTC on a clear day. Mean ozone values over Samoa are similar to those measured 20–30 years ago over Panama. Ozone is higher over the tropical South Atlantic (Natal) than over the western Pacific (Samoa) all year from about hPa to the tropopause; ozone is most similar in May and June over the Atlantic and Pacific, the months with minimum burning in the tropics.

Polar ozonesonde profiles provide a detailed vertical measurement of ozone that can be made during low sun angle and dark time periods, when satellite ozone observations are limited.

However, the cold, dark winter time will reduce the altitude burst elevation of the rubber weather balloons. Ozone data were gathered over mid-latitude western North America term observations within A27,28 show ozone increase above western North America, and previous ozonesonde analyses.

[1] Ozonesonde observations from Syowa and the South Pole over more than 40 years are described and intercompared. Observations from the two sites reveal remarkable agreement, supporting and extending the understanding gained from either individually.

Both sites exhibit extensive Antarctic ozone losses in a relatively narrow altitude range. She also led the and INTEX Ozonesonde Network Study campaigns in the first strategic NRC Staff ozonesonde sampling over North America.

ozonesonde station before September that provided continuous data over the Indochina Peninsula, which is located at the southeastern edge of the Eurasian Continent.

[5] Since Septemberwe have conducted once or twice monthly regular ozonesonde observations in Hanoi (ıN, ıE) at the base of the Indochina Penin-sula. Decadal trend of deseasonalized monthly-mean hPa ozone mixing ratio (unit: ppbv decade-1) at five ozonesonde stations: observation (black), MACCRA (red), CAMSRA (green), JRA (purple), TCR-2 (pink), ERA5 (orange), CFSR (light blue), and MERRA2 (blue): a, b for 10 years over – and c, d for 15 years over – Note that.

FLEXPART required hourly wind fields produced by a regional analysis model called run at ° × ° resolution on a domain covering North America. A well-designed network of ozonesonde stations answers questions that cannot be solved by short campaigns or current satellite technology.

Short-term strategic networks operated over North America in July—August within the Ozone in the Pacific tropical troposphere from ozonesonde observations. Journal Geophysical Research,   Ozonesonde observations are averaged over the regions in Fig.

Therefore, this study utilizes this global dataset for analysis of hPa geopotential height and wind speed over a domain that covers the eastern North Pacific Ocean and most of North America, and for a vertical cross-section analysis of PV and wind speed to show the occurrence of the SI events over Northern California during a period of Book.

Feb ; Irina Petropavlovskikh against ozonesonde observations in North America for the year tropospheric ozone concentrations that have occurred over western North American.

The design and test results of a simple single-beam ultraviolet photometer for ozone measurements are presented. The instrument has several features that distinguish it from former UV absorption instruments, all of which contribute to a smaller size and much lower power consumption while retaining the advantages of the UV measurement technique.

A novel airflow system and advanced. Mean vertical profiles of CO, NO x, PAN, and O 3 concentrations over the Northeast Pacific during INTEX-B (April-May ). Observations (black) from the DC8 (top) and C (bottom) aircraft are.Abstract.

Ozone profiles obtained by near-daily ozonesonde observations during campaigns at several sites in the North Atlantic are used to construct time-height cross sections of ozone concentration through the troposphere.

Strong day-to-day ozone variability on the scale of synoptic meteorological disturbances is found both in the spring.Validation of these satellite observations has been limited to aircraft in situ measurements over the eastern United States (Taubman et al. ) and eastern China (Dickerson et al. ; Krotkov et al.
